Description

The present disclosure relates to a projection instruction device, a projection instruction system, and a plan data management system that support the sorting of packages.

With the rise of economic activity in recent years, the amount of luggage distributed is increasing. In the parcel distribution process, the sorting work of sorting parcels according to destination tends to be a manual work, which is a time-consuming process depending on the skill level of the workers. In SCM (Supply Chain Management), the distribution of parcels is a very important factor, and it is expected that the efficiency of SCMs will be improved by streamlining the parcel sorting work. In view of such circumstances, a technique for automating at least a part of the sorting work has also been proposed (see, for example, Patent Document 1).

That is, the "distance image" may be any information indicating the relationship between the coordinates and the distance in the captured area, and its data structure does not matter. In the present disclosure, the distance image sensor 22 is used to identify the position of the luggage. Therefore, the distance image sensor 22 can be replaced by another sensing device (ultrasonic sensor, infrared sensor, stereo camera, monocular video camera).

The color image sensor 24 captures the baggage on which the distance image is generated and generates the color image. The "color image" refers to an image expressing the color of the surface of the luggage with a predetermined gradation, and the "gradation" includes not only 256 gradations of RGB but also all kinds such as gray scale. In the present disclosure, the color image sensor 24 is used to track each package with respect to the package specified by the distance image sensor 22. The color image sensor 24 can also be replaced by another sensing device (ultrasonic sensor, infrared sensor, stereo camera, monocular video camera).

That is, in the present disclosure, the term "image" includes both distance images and color images. In the present disclosure, information output from an image sensor as a sensing device including a distance image sensor and a color image sensor is referred to as sensing information. In the present embodiment, an image sensor 20 (including the distance image sensor 22 and the color image sensor 24) will be used as an example of the sensing device. Further, in the present embodiment, as an example of sensing information, a distance image which is an output of the distance image sensor 22 and a color image which is an output of the color image sensor 24 will be used for explanation.

FIG. 2 is a conceptual diagram showing a situation in which the parcel sorting system 100 installed in the distribution center is operating. The label reader 10 arranged above the conveyor 50 reads the label affixed to each load P conveyed by the conveyor 50. The label contains label record information, including various information about the package. The label record information includes information similar to the package identification number, the sender's name, address, telephone number, recipient's name, address, telephone number, package type, etc., which are individually assigned to the package. The label may be read by the worker in charge by manually touching the barcode in the label with a barcode reader as the label reader 10.

Further, the image sensor 20 captures an image (distance image and color image) of the luggage P conveyed by the transport conveyor 50, and the position of the luggage P, the distance to the luggage P, and the size of the luggage P (the luggage P is a rectangular parallelepiped). In this case, the length of three sides), the color of the luggage P, the pattern of the luggage P, and the like are acquired. The arrangement position of the label reader 10 and the image sensor 20, the type of the sensing device, and the processing order are not particularly limited to the illustrated form. In this example, the image sensor 20 and the projector 40 are constructed as an integrated imaging and projection device 60, and are arranged above the conveyor 50.

The projection instruction device 30 is composed of, for example, a computer arranged in the vicinity of the conveyor 50 or in another room, and includes information for identifying the luggage acquired by the label reader 10 and a distance image and a color image generated by the image sensor 20. Based on the above, a projected image to be displayed on the luggage P (for example, the upper surface when the luggage P is a rectangular parallelepiped) is generated. The projection instruction device 30 sends a projection instruction to the projector 40 to project the projected image onto the luggage P. Upon receiving the projection instruction, the projector 40 projects the projected light including the projected image generated by the projection instruction device 30 onto the luggage P, and displays the projected image on the luggage P.

In the present disclosure, the "image projection device" is not limited to a device that directly projects a light beam onto a baggage. In the present disclosure, the "image projection device" also includes eyeglasses capable of displaying an image.

It also includes making the operator recognize that the projected light is projected on the luggage. That is, when the worker wears special spectacles capable of displaying an image, the projected image here may be superimposed on the image of the luggage P visually recognized through the spectacles.

A worker M in charge of picking up the load stands beside the transfer conveyor 50, and picks up the load that has reached its own area from the transfer conveyor 50 and loads it onto the waiting truck.

For example, the label attached to the baggage P1 includes, for example, baggage identification information of "AAA111" as label record information. It is specified that the package identification information of "AAA111" is to be sorted in a specific area. Therefore, when the package P1 arrives at the specific area, the processor 34 transmits the data of the projected image generated based on the package identification information of the package P1 to the projector 40. The projector 40 projects the projected image onto the luggage P1.

(Outline of operation)
Hereinafter, the basic operation of the luggage sorting system 100 will be described. FIG. 16 is a flowchart showing an example of an outline procedure of operations mainly performed by the projection instruction device 30 according to the first embodiment, particularly the processor 34 of the projection instruction device 30.

In FIG. 16, first, after reading the label recording information of the baggage label by the label reader 10, the input unit 32 of the projection instruction device 30 acquires the baggage identification information corresponding to the label recording information from the label reader 10 (S1). .. The package identification information is at least one of the information similar to the package identification number, the sender's name, address, telephone number, recipient's name, address, telephone number, package type, etc., which are individually assigned to the package. This is information that includes one. The processor 34 assigns an ID as a package identification number for identifying the package to the package identification information, and records the ID in the memory 36 together with the time information corresponding to the time when the ID is assigned (S2). The ID recorded in the memory 36 may be the package identification number originally recorded in the package identification information, or the projection instruction device 30 may generate and assign a new ID.

On the other hand, in parallel with step S1 and step S2, after the image sensor 20 captures the image of the luggage, the input unit 32 of the projection instruction device 30 acquires the image as sensing information from the image sensor 20 (S20). The processor 34 determines whether or not the ID corresponding to the baggage existing in the image exists in the memory 36 (S30).

As an example of the method of determining whether or not the ID corresponding to the baggage existing in the image exists in the memory 36, the following procedure can be mentioned. That is, the processor 34 is required for the load to move between the label reader 10 and the image sensor 20 due to the distance (known) between the label reader 10 and the image sensor 20 and the speed of the conveyor 50. Calculate the time. Then, the processor 34 subtracts (that is, subtracts) the calculated time from the time when the image is acquired, so that the time when the baggage existing in the image is given an ID by the label reader 10 (and the processor 34) is estimated. it can. Then, the processor 34 can estimate that the ID given in the vicinity of the estimated time is the ID corresponding to the package existing in the image. Further, as another example, there is a method of installing another image sensor in the vicinity of the label reader 10. That is, from the time when the label reader 10 assigns the ID (and the processor 34), the luggage to which the ID is assigned is tracked by using another image sensor installed near the label reader 10, so that the luggage is assigned at each time. Measure the distance between (and ID) and the label reader 10. The processor 34 determines a predetermined step from the distance between the measured luggage (and ID) and the label reader 10, the distance of the luggage in the image acquired in step S20, and the distance between the two image sensors (known). The ID of the package in the image acquired in S20 can be estimated.

In this way, the processor 34 determines whether or not the ID corresponding to the package included in the image exists in the memory 36 (S30). That is, as described in step S2, the time information corresponding to the baggage identification information, the ID, and the time when the ID is assigned is recorded in the memory 36 in advance. On the other hand, the processor 34 exists in the image by subtracting (that is, subtracting) the time required for the luggage to move between the label reader 10 and the image sensor 20 from the time when the image is acquired, for example, as described above. It is possible to estimate the time when the baggage to be loaded is given an ID by the label reader 10 (and the processor 34). The processor 34 compares the time information recorded in the memory 36 in advance with the estimated time, and if these values are close to each other (for example, when the time difference is equal to or less than a predetermined threshold time), the processor 34 corresponds to the luggage included in the image. It can be determined that the ID to be used exists in the memory 36. When it is determined that the ID corresponding to the baggage exists in the memory 36 (S30; Yes), the process proceeds to the process of step S60 and subsequent steps.

When it is determined that the ID corresponding to the package does not exist in the memory 36 (S30; No), the processor 34 relocates the package on the premise that the ID is not assigned to the package (S40). , An ID is given to the package (S50). The details of steps S30 to S50 will be described later.

Further, the processor 34 tracks the ID-attached load that is conveyed and moved by the transfer conveyor 50 based on the image from the image sensor 20 acquired by the input unit 32 at predetermined intervals (S60). Further, the processor 34 generates a projected image in parallel with tracking the package and transmits it to the projector 40 (S70). It should be noted that the projected image may not be generated all the time, but may be generated only when the luggage exists in the area to be picked up. Further, the image projected on the luggage may be switched depending on whether or not the luggage has been picked up by the operator. Whether or not the package has been picked up can be determined by analyzing the image taken by the image sensor 20. Further, as an example of the image projected when the package is picked up, detailed information of the package can be mentioned.

The projector 40 that has acquired the projected image from the projection instruction device 30 projects the projected image onto the corresponding baggage.

(Correction of projection position)
As shown in FIG. 16, in the package sorting system 100, the package tracking (S60), the projection image generation (S70), and the projection process are performed in parallel. On the other hand, since the process required for tracking the package includes the process of acquiring and analyzing the image, the load is generally larger than the process of generating the projected image. Therefore, when the projected image is projected according to the position of the package updated by the tracking of the package, the position where the projected image is projected is updated only at the update frequency of the tracking of the package. As a result, from the operator's point of view, the projected image appears to move suddenly after being stopped for a certain period of time (the period required for updating the position by tracking the luggage).

FIG. 17 is a diagram schematically showing this problem. FIG. 17 is an explanatory diagram of an example of the projected position on the luggage. In FIG. 17, the solid line in the upper row shows the actual position of the luggage, and the broken lines in the upper and lower rows indicate the position of the luggage recognized by the luggage sorting system 100 by the processing of tracking the luggage. Further, TS1 to TS4 are time stamps indicating a time.

FIG. 17 shows a transition when it is assumed that the package tracking cycle is performed every 3 hours and the package projection process is performed every hour. That is, at time TS2 and time TS3, the position of the luggage is not updated (indicated by diagonal lines in the lower part of FIG. 17), while the luggage moves at any time and the projected image is projected every hour. As a result, as shown in the upper part of FIG. 17, at the time TS2 and the time TS3, the position where the projected image is projected deviates from the actual position of the luggage. Then, when the position of the luggage is updated at the time TS4, the position where the projected image is projected suddenly moves.

In order to solve this problem, the luggage sorting system 100 performs a process of correcting the projected position of the luggage.

Specifically, when the moving speed of the luggage (transporting speed by the transport conveyor 50) is v, the moving distance D of the luggage is (current time-the time when the position of the luggage was updated most recently) × v. Can be calculated by. The processor 34 may calculate the moving distance D as a directional distance (eg, 2 cm in the east direction), or when the moving direction of the load is substantially the same as the transport direction of the transport conveyor 50. May be calculated as a distance in which no particular direction is determined (that is, in order to calculate the moving distance D as a directional distance, v may be calculated as a directional speed). The predicted projection position of the load on which the projected image should be projected can be obtained by adding D to the position of the image. In the following, unless otherwise specified, the expressions "distance" and "velocity" will be described as a general term for those with a direction and those without a direction.

In order to enable the calculation of the distance D described above, it is necessary to determine the value of the velocity v by estimation or actual measurement. The following method can be used to determine the value of the velocity v.

Method 1) When tracking a package (step S60), v is calculated from the travel distance and direction per hour.
Method 2) It is assumed that the load moves in a predetermined speed and direction, and the speed is defined as v.
Method 3) Monitor the transport speed and direction of the conveyor from the output of the motor, etc., and set the speed to v (assuming that the speed of the load is the same as that of the conveyor).

Further, the value of v may be determined by comprehensively evaluating the results calculated by each method, instead of calculating by any one of the methods 1) to 3). For example, it is conceivable that the average value of the results calculated by each of the methods 1) to 3) is v.

Further, in the method 2) in which the speed and direction of the luggage are regarded as predetermined in advance and the method 3) in which the speed is calculated from the transport speed of the conveyor, the speed can be estimated from the beginning of the operation of the luggage sorting system 100. On the other hand, in the method 1) of calculating the speed from the tracking result of the baggage, the speed cannot be estimated until a certain amount of time has passed. On the other hand, in the method 1), since the actual movement of the luggage can be reflected in the speed v regardless of the transport direction of the conveyor, the luggage is moved due to the collision between the luggage or the worker touches the luggage. Even if the vehicle moves in a direction different from the conveyor transport direction, the projection position can be corrected to a position that follows the actual movement. Specifically, in the method 1), the projection position can be corrected even if the load moves vertically or diagonally with respect to the conveyor transport direction, or the load moves backward in the conveyor transport direction.

In consideration of the characteristics of each of these methods, for example, the method to be used may be switched according to the elapsed time, or the degree of reflection in the evaluation may be changed, such as changing the weight of the weighted average. That is, the advantages of each method can be utilized by mainly using the method 2) and the method 3) immediately after the start of the baggage sorting system 100 and mainly using the method 1) after a lapse of time. ..

By correcting the position where the projected image should be projected in this way, according to the first embodiment, the projector 40 can project the projected image on the load more accurately along the movement thereof. , The projection of the image looks smooth even from the human eye.

In addition, D may be calculated by D = (current time + Δt-the time when the position of the luggage was updated most recently) × v. Here, Δt can be the transmission time of the projected image from the projection instruction device 30 to the projector 40. Alternatively, Δt can be a delay time due to processing inside the projector. Alternatively, Δt can be the time obtained by adding the delay time due to the processing inside the projector to the transmission time of the projected image from the projection instruction device 30 to the projector 40. By determining Δt in this way, the predicted projection position can be calculated more accurately.

FIG. 3 is a diagram showing a state in which a projected image including information such as characters and numbers is projected on the upper surface of the luggage. When the worker M sees the projected image projected on the luggage P1 and confirms that it is the luggage he is in charge of, he immediately loads the arrived luggage P1 onto the truck. Therefore, the sorting work can be performed efficiently. The same applies to the luggage P2.

FIG. 4 is a diagram showing a UI screen 350 displayed on the display unit 312 of the truck transport management device 300. When the projection instruction device 30 detects that the loaded load on which the projected image is projected has been loaded on the truck (for example, an input operation from a worker, a determination based on the output of the image sensor 20), the image sensor 20 determines. The package identification information including the detected package capacity information is sent to the server 200. The server 200 acquires the package identification information including the package capacity information from the package sorting system 100 via the network NW1, and calculates the current occupied capacity of the truck for each truck with a different delivery destination in real time. The server 200 creates a UI screen 350 showing the result of calculating the current occupied capacity of the truck for each truck, and sends it to the truck transportation management device 300 or the warehouse control device 400. Upon receiving the data on the UI screen 350, the truck transport management device 300 displays the UI screen 350 on the display unit 312. Further, when the warehouse control device 400 receives the data of the UI screen 350, the warehouse control device 400 displays the UI screen 350 on the display unit 412.

On the UI screen 350, for example, for five trucks, a truck icon, truck information, a bar display indicating the occupied capacity of the truck, a current luggage capacity ratio calculated from the size of the loaded luggage, and the loaded luggage capacity are displayed. The current baggage volume ratio calculated from the number of packages is displayed in multiple columns. For example, in the case of the first truck on the top row, in addition to the truck icon and truck information, a bar display showing the occupied capacity of the truck with an orange gradation, luggage capacity ratio: 31%, luggage amount ratio: 32/100. Shown.

A truck delivery manager or a sorting worker can intuitively grasp the size of the load loaded on the truck bed by looking at the UI screen 350. For example, a truck delivery manager or a sorting worker can roughly grasp how much of the package to be transported is loaded on the current truck and from where on the next truck, and can improve his / her work efficiency. In addition, the truck delivery manager can more accurately plan the number of trucks required for loading, that is, the number of trucks arranged, based on the current occupied capacity of the truck. For example, if there is a lot of luggage, the truck delivery manager can prepare the next truck. On the other hand, when the package is small, the truck delivery manager does not have to prepare a truck to wait. Therefore, there is no waste in arranging trucks.

The display device that displays the UI screen showing the current occupied capacity of the truck is not limited to the display unit 312 of the truck transportation management device 300, but also the display unit 212 of the server 200, a smartphone, a tablet terminal, etc. that can be connected to the server 200. It may be a display or a monitor connected to the projection instruction device 30.

In addition, the truck delivery manager can dynamically increase the income of the truck driver who carries a large amount of luggage based on the loading status of the truck displayed on the UI screen. Dynamic pricing (in other words, dynamic increase in wages to truck drivers) may be performed. When there is a lot of luggage, the projection instruction device 30 inserts a message such as "Ganbare" or "Break in 2 minutes" on the belt conveyor so as not to overlap the luggage in the projected image projected by the projector 40. However, measures such as improving the motivation of the sorting workers or changing the mood may be taken.

Next, the operation of the projection instruction system 5 according to the first embodiment will be shown.

Here, the case where the projection instruction system 5 performs a baggage sorting operation based on the baggage identification information is shown. It should be noted that the change of the baggage identification information including the sorting information conceptually includes addition, change, and deletion.

[Usage example 1 of projection instruction system]
(Normal luggage sorting)
FIG. 5 is a diagram showing a procedure of a luggage sorting operation in the projection instruction system 5. In normal baggage sorting, in principle, a different person in charge sorts the baggage for each destination. Each person in charge determines the destination of the luggage based on the projected image projected on the upper surface of the luggage. The projected image is a circular image projected on the upper surface of the luggage. The circular image is filled with a different color for each destination. At the center of the circle image, the person in charge number for identifying the person in charge is described. In the present embodiment, when the colors of the circular image are "blue", "green", and "yellow", it means that the destinations are "Tokyo", "Osaka", and "Hokkaido", respectively. If the person in charge number is "1", "2", or "3", the person in charge of sorting the luggage bound for Tokyo M1, the person in charge of sorting the luggage bound for Osaka M2, the person in charge of sorting the luggage bound for Hokkaido Indicates that it is M3 (see FIG. 6). When the sorting destination is not particularly distinguished, the person in charge of sorting is simply referred to as a worker M. A circular image is illustrated as an example of the projected image, but the circular image does not necessarily have to be circular, and may have any shape such as a quadrangle or a polygon.

The projection instruction device 30 reads the label attached to the package transported by the transport conveyor by the label reader 10 and acquires the package identification information including the information such as the destination of the package. Further, the projection instruction device 30 takes an image of the load transported by the transport conveyor by the image sensor 20 and acquires information such as the quantity of the load and the capacity of the load. The projection instruction device 30 transmits information such as the destination of the package, the quantity of the package, and the capacity of the package to the server 200 connected to the network NW1 by the communication circuit 39 (T1).

In the processor 210 of the server 200, as the person in charge information for sorting ordinary packages, the person in charge M1 sorts the packages bound for Tokyo, the person in charge M2 sorts the packages bound for Osaka, and the person in charge M3 sorts the packages bound for Hokkaido. The sorting is registered in the memory 211. In addition, the baggage sorting system 100 may register the person in charge information for sorting normal parcels in the memory.

On the other hand, the processor 210 of the server 200 periodically acquires weather information and traffic information from an external organization as external information (T2). For example, if the weather information predicts that a typhoon will come to Tokyo, there will be a situation where you want to hurry to sort your luggage to Tokyo. Traffic information includes traffic congestion information.

Further, the processor 210 of the server 200 acquires the package information from the warehouse control device 400 via the network NW3 (T3). For example, if there is a lot of luggage bound for Tokyo tomorrow, or if there is a lot of luggage bound for Tokyo for an hour from now, there will be a situation where you want to sort the luggage bound for Tokyo in a hurry.

Further, the processor 210 of the server 200 acquires the truck arrangement information, the scheduled truck loading capacity, and the delivery route information from the truck transportation management device 300 via the network NW2 (T4).

The processor 210 of the server 200 determines the change of the sorting work for the worker based on the information such as the destination of the luggage, the quantity of the luggage, and the capacity of the luggage received from the projection instruction device 30 in the procedure T1. The processor 210 outputs the package identification information including the changed sorting information to the package sorting system 100. In the changed baggage identification information, the processor 210 tells the person in charge M2 who sorts the baggage to Osaka, for example, to sort the baggage to Tokyo in a hurry, in addition to the baggage to Osaka, to Tokyo. The package sorting system 100 is instructed to sort the packages via the network NW1 (T5).

When the projection instruction device 30 of the luggage sorting system 100 receives this instruction via the communication circuit 39, the person in charge M1 sorts the luggage bound for Tokyo to the projector 40 as the luggage identification information including the changed sorting information. Then, the person in charge M2 sorts the luggage bound for Osaka and Tokyo, and the person in charge M3 instructs the projection of the projected image so as to sort the luggage bound for Hokkaido.

FIG. 6 is a diagram showing an example of the projection pattern Q1 projected on the upper surface of the luggage. Usually, in the sorting of packages, the sorting of packages at the delivery destination tends to be biased from the forecast of the next day and real-time information. For example, if the person in charge M1 sorts a lot of luggage for Tokyo, it is possible to ask the person in charge M2 for Osaka to help. In the projection pattern Q1, the projector 40 projects a projected image including help on the upper surface of the package so that the person in charge M2 bound for Osaka sorts the package bound for Tokyo.

Here, in the package identification information including the sorting information before the change, the projector 40 fills in blue (dotted display in the figure) for the package bound for Tokyo that is first transported by the transport conveyor, and the person in charge number “1”. Projects the projected image Gb, which is a circular image of. The projector 40 projects a projected image Gb, which is a circular image of the person in charge number “2”, painted in green (hatched display in the figure) on the luggage bound for Osaka, which is secondly transported by the transport conveyor. The projector 40 projects a projected image Gb, which is a circular image of the person in charge number “3”, painted in yellow (displayed in white in the figure) on the package bound for Hokkaido, which is thirdly transported by the transport conveyor.

In the package identification information including the changed sorting information, the projector 40 fills in blue with the package bound for Tokyo that is first transported by the transport conveyor, and displays the projected image Ga, which is a circular image of the person in charge number “1”. Project. The projector 40 fills in green on the package bound for Osaka, which is secondly transported by the transport conveyor, and projects a projected image Ga, which is a circular image of the person in charge number “2”. Further, the projector 40 paints the luggage bound for Tokyo, which is thirdly conveyed by the conveyor, in blue, and projects the projected image Ga, which is a circular image of the person in charge number “2”. As a result, the person in charge M2 with the person in charge number "2" who normally sorts the luggage bound for Osaka will sort both the luggage bound for Tokyo and the luggage bound for Osaka. As a help screen for the person in charge of sorting luggage bound for Osaka to help sort the luggage bound for Tokyo, here, the projected image is a circle image of the person in charge number "2", filled in blue. Ga is projected, but instead of being filled with blue, it may be a projected image in which blue blinks. The projector 40 fills in yellow on the package bound for Hokkaido, which is fourth conveyed by the conveyor, and projects a projected image Ga, which is a circular image of the person in charge number “3”.

The processor 210 of the server 200 instructs the truck transport management device 300 to arrange a truck via the network NW2 according to the package identification information including the changed sorting information (T6). Upon receiving this instruction, the truck transport management device 300 displays the truck arrangement information on the display unit 312 and also instructs the truck to be delivered.

Further, the processor 210 of the server 200 outputs the changed sorting information to the warehouse control device 400 via the network NW3 (T7). The warehouse control device 400 displays the changed sorting information on the display unit 412.

In this way, in the projection instruction system 5, when a projected image including sorting information is projected on the upper surface of the package, the person in charge of sorting is represented by the number superimposed on the projected circular image, and the sorting destination is represented by the color of the circular image. To express. As a result, the sorting worker can easily recognize the person in charge of the sorted package and the delivery destination. In addition, when the amount of parcels sorted by a specific parcel sorting destination is large, the projection instruction device assigns a worker who sorts the parcels of another sorting destination to a specific parcel sorting, and assigns a worker who sorts the specific parcel. You can instruct them to support you. Therefore, the projection instruction device can equalize the labor of the sorting workers. In addition, delays in sorting packages to a specific sorting destination are suppressed.

FIG. 7 is a diagram showing another example of the projection pattern projected on the upper surface of the luggage. When sorting a large number of packages bound for Tokyo, the processor 210 of the server 200 may assign a vacant person M2 to the package sorting system 100 to temporarily sort the packages bound for Tokyo. In this case, the projection instruction device 30 instructs the projector 40 to paint in blue and project a circular image of the person in charge number: "2" on the upper surface of the package. As a result, the number of people in charge of sorting the luggage bound for Tokyo will increase by one, and the sorting work of the luggage bound for Tokyo will be improved.

FIG. 8 is a diagram showing another example of the projection pattern projected on the upper surface of the load. In the situation where there is a person in charge M1 who sorts the luggage bound for Osaka and a person in charge M2 who sorts the luggage bound for Hokkaido, when the sorting work for sorting the luggage bound for Tokyo is entered, the processor 210 of the server 200 has a small amount of luggage bound for Osaka. In this case, the person in charge M1 who sorts the luggage bound for Osaka may be assigned to sort the luggage bound for Tokyo. In this case, the projection instruction device 30 paints the projector 40 in green, projects a circular image of the person in charge number: "1" on the upper surface of the luggage bound for Osaka, paints it in blue, and the person in charge number: "1". Instruct to project the circle image of the above on the upper surface of the luggage bound for Tokyo. This allows one person in charge to sort both packages bound for Osaka and packages bound for Tokyo.

(Assortment of urgent luggage)
FIG. 9 is a diagram showing a procedure of an urgent baggage sorting operation in the projection instruction system 5. The projection instruction device 30 of the baggage sorting system 100 reads the label attached to the baggage transported by the transport conveyor by the label reader 10 and acquires the baggage amount, the load rate, and the baggage handling information for each destination (T11). The projection instruction device 30 transmits the acquired information to the server 200 connected to the network NW1 by the communication circuit 39.

The processor 210 of the server 200 periodically acquires weather information and traffic information from an external organization as external information. For example, if the weather information predicts that a typhoon will come to Hokkaido, there will be a situation where you want to hurry to sort your luggage bound for Hokkaido. The processor 210 urgently designates a package destined for a specific destination (here, Hokkaido) (T12). As an urgent designation, there are cases where a typhoon is approaching due to weather information, and cases where an event is held near the delivery route and traffic congestion is expected.

The processor 210 of the server 200 acquires the package information from the warehouse control device 400 via the network NW3 (T13). For example, as baggage information, the processor 210 includes the sorting amount, the number of packages currently or daily, and worker information. Worker information includes the number of workers and their proficiency.

The processor 210 of the server 200 acquires the truck arrangement information, the scheduled truck loading capacity, and the delivery route information from the truck transport management device 300 via the network NW2 (T14).

Based on the information urgently specified in the procedure T12, the processor 210 of the server 200 instructs the package sorting system 100 to urgently specify the package bound for Hokkaido as the changed sorting information (T15).

When the projection instruction device 30 of the luggage sorting system 100 receives this instruction via the communication circuit 39, the person in charge M1 sorts the luggage bound for Tokyo to the projector 40 as the changed sorting information, and the person in charge M2 Sorts the luggage bound for Osaka, and when the person in charge M3 sorts the luggage bound for Hokkaido, instructs the person in charge to urgently specify the luggage bound for Hokkaido and project the projected image.

FIG. 10 is a diagram showing a projection pattern Q2 projected on the upper surface of an urgent luggage. In this projection pattern Q2, the projector 40 fills in blue with the luggage bound for Tokyo that is first conveyed by the conveyor, and projects the projected image Ga, which is a circular image of the person in charge number “1”. The projector 40 fills in green on the package bound for Osaka, which is secondly transported by the transport conveyor, and projects a projected image Ga, which is a circular image of the person in charge number “2”. The projector 40 normally fills the baggage bound for Hokkaido, which is transported third by the transport conveyor, with yellow and projects a projected image Gb which is a circular image of the person in charge number “3”. However, in the case of urgent designation, the projector 40 fills in red (cross display in the figure), projects the characters "Urgent", and projects the projected image Ga which is a circular image of the person in charge number "3". The person in charge of sorting the luggage bound for Hokkaido, M3, sees the projected image Ga, which is a circular image of the characters "Urgent", which is projected on the upper surface of the luggage and is conspicuous in red. Can respond quickly to sorting.

The processor 210 of the server 200 instructs the truck transport management device 300 to arrange a truck via the network NW2 according to the changed sorting information including the information of the urgently designated package (T16). Upon receiving this instruction, the truck transportation management device 300 displays the truck arrangement information on the display unit 312 and also instructs the truck to be delivered.

Further, the processor 210 of the server 200 outputs the changed sorting information changed so as to preferentially sort the packages in Hokkaido to the warehouse control device 400 via the network NW3 (T17). The warehouse control device 400 displays the changed sorting information on the display unit 412.

In this way, in the projection instruction system 5, the projection instruction device can instruct to give priority to the work of the sorting destination that must be urgent.

(Sorting of luggage in consideration of truck arrangements)
FIG. 11 is a diagram showing a procedure of a luggage sorting operation in consideration of truck arrangement in the projection instruction system 5. The projection instruction device 30 of the luggage sorting system 100 reads the label attached to the luggage conveyed by the transfer conveyor by the label reader 10 and acquires the luggage amount, the loading rate, and the luggage handling information for each destination (T21). The projection instruction device 30 transmits the acquired information to the server 200 connected to the network NW1 by the communication circuit 39.

The processor 210 of the server 200 periodically acquires weather information and traffic information from an external organization as external information (T22).

The processor 210 of the server 200 acquires the package information from the warehouse control device 400 via the network NW3 (T23). For example, as baggage information, the processor 210 includes the sorting amount, the number of packages currently or daily, and worker information. The worker information includes the number of workers and the skill level.

The processor 210 of the server 200 acquires the truck arrangement information, the scheduled truck loading capacity, and the delivery route information from the truck transport management device 300 via the network NW2 (T24).

Based on the truck arrangement information, the planned truck loading capacity, and the delivery route information acquired in step T24, the processor 210 of the server 200 sets the destination of the luggage as luggage identification information including the changed sorting information. The luggage sorting system 100 is instructed to specify the loading position of the corresponding truck on the loading platform (T25). For example, if the delivery route of the truck is departure point: Osaka, waypoint point: Yokohama, arrival place: Tokyo, the processor 210 specifies the loading position of the luggage for Tokyo in the back of the truck bed, and goes to Yokohama in front. Specify the loading position of the luggage.

When the projection instruction device 30 of the luggage sorting system 100 receives this instruction via the communication circuit 39, the projection instruction device 30 displays a circular image in front of the projector 40, which specifies the loading position of the luggage bound for Yokohama as the changed sorting information. Instruct a projection image and a projection image, which is a circular image that specifies the loading position of luggage bound for Tokyo, to be projected on the back.

FIG. 12 is a diagram showing a projection pattern Q3 projected on the upper surface of the load whose loading position is designated. In this projection pattern Q3, the projector 40 fills in blue with the luggage bound for Yokohama that is first transported by the transport conveyor, and projects a projected image that is a circular image with the characters "front" and the person in charge number "1". To do. The letters "front" indicate that the loading position of the luggage is in front of the loading platform. In addition, the projector 40 fills in blue with the luggage bound for Tokyo, which is secondly conveyed by the conveyor, and projects a projected image which is a circular image of the characters "rear" and the person in charge number "1". The projector 40 paints the luggage bound for Osaka, which is thirdly transported by the transport conveyor, in green and projects a projected image which is a circular image of the person in charge number “2”. Here, the loading position of the luggage with respect to the truck bed is represented by the simple characters "front" and "rear", but it is represented by illustrations (illustration representing the front, illustration representing the back), colors, fonts, etc. You may.

The processor 210 of the server 200 loads the same truck with different loading positions to the truck transport management device 300 via the network NW2 according to the changed sorting information including the information of the luggage whose loading position is specified. Instruct trucks to be arranged for loading (T26). Upon receiving this instruction, the truck transportation management device 300 displays the truck arrangement information on the display unit 312 and also instructs the delivery of the truck.

Further, the processor 210 of the server 200 outputs the changed sorting information to the warehouse control device 400 via the network NW3 so as to load the same truck with different loading positions (T27). The warehouse control device 400 displays the changed sorting information on the display unit 412.

In this way, in the baggage sorting system 100, for example, it is assumed that the baggage is loaded on a truck bound for Tokyo, where the departure point is Osaka, the waypoint is Yokohama, and the arrival point is Tokyo. The projection instruction device instructs the upper surface of the luggage bound for Yokohama to project a projected image with the word "front" on the upper surface of the luggage, which prompts the luggage to be placed in front of the truck bed. In addition, the projection instruction device instructs to project a projected image containing the characters "rear" on the upper surface of the luggage, which prompts the luggage to be placed on the back of the truck bed. The worker who sorts the luggage loads the luggage on which the projected image containing the characters "front" is projected in front of the truck bed. In addition, the worker loads the luggage on which the projected image containing the characters "rear" is projected into the back of the truck bed. As a result, when the departure point, the waypoint, and the arrival point are set as the delivery route, the work efficiency of loading and unloading is improved when the driver who delivers the truck unloads the luggage locally.

(Sorting of luggage in consideration of luggage handling information)
In the projection instruction system 5, the label reader 10 of the luggage sorting system 100 reads the label attached to the luggage, and the projection instruction device 30 transmits the read luggage amount, loading rate, and luggage handling information for each destination to the server 200. .. The processor 210 of the server 200 changes the package identification information including the sorting information in consideration of the handling of the package based on the package handling information acquired from the package sorting system 100. The processor 210 transmits the baggage identification information including the changed sorting information to the projection instruction device 30. The projection instruction device 30 instructs the projector 40 to project a projected image in consideration of the baggage handling information on the baggage based on the changed sorting information.

The processor 210 of the server 200 may acquire the package handling information from the warehouse control device 400, the truck transportation management device 300, and the like.

FIG. 13 is a diagram showing a projection pattern Q4 projected on the upper surface of the luggage in consideration of the luggage handling information. In this projection pattern Q4, the projector 40 paints the first package to Tokyo transported by the conveyor in blue, and displays the characters "Caution" and the projected image Ga which is a circular image of the person in charge number "1". Project. The word "caution" indicates that you need to be careful when sorting your luggage. Further, the projector 40 paints the luggage bound for Osaka, which is secondly transported by the transport conveyor, in green as usual, and projects the projected image Ga, which is a circular image of the person in charge number “2”. Here, the characters "Caution" are projected as part of the circular image, but other characters such as "Handle carefully" and "Walemono", and illustrations or symbols indicating caution are used as baggage handling information. It may be projected. In addition, the baggage handling information may be expressed by blinking the circular image.

In this way, in the projection instruction system, the projection instruction device calls attention to the luggage of VIPs (Very Important Person), the luggage in which fragile items are packed, and other luggage that requires special attention to sorting. Can be prompted.

(Sort of luggage when loading on the next truck)
In the projection instruction system 5, the processor 210 of the server 200 sorts the delivered cargo on the loading platform of the next truck based on the truck loading capacity and the truck arrangement information received from the truck transport management device 300. Change the information. The processor 210 transmits the baggage identification information including the changed sorting information to the projection instruction device 30. The projection instruction device 30 instructs the projector 40 to project the projected image instructed to be loaded on the next truck on the luggage based on the luggage identification information including the changed sorting information.

FIG. 14 is a diagram showing a projection pattern Q5 projected on the upper surface of the luggage when it is loaded on the next truck. In this projection pattern Q5, the projector 40 projects a projected image Ga, which is a circle image of the characters “NEXT” and the person in charge number “1”, painted in blue on the luggage transported by the transport conveyor to Tokyo. The letters "NEXT" indicate that the current truck is full and encourages the next truck to be loaded.

Further, the projector 40 paints green on the luggage bound for Osaka, which is secondly transported by the transport conveyor, and projects the projected image Ga, which is a circular image of the person in charge number “2”, as usual. Here, the characters "NEXT" were projected as part of the circle image, but as the next track information, other characters such as "From here to the next track", "Change track", and the following Illustrations or symbols representing track information may be projected. Further, the next track information may be expressed by blinking the circular image. In this case, by making the blinking pattern of the circular image different from the blinking pattern of the baggage handling information, the sorting worker can easily recognize the next truck information.

As described above, in the luggage sorting system 100, the projection instruction device can instruct the worker in real time to load the trucks to be sorted into the next truck because the trucks currently being loaded are full. Therefore, the worker can easily recognize that the load is to be loaded on the next truck and sort the luggage. This increases the efficiency of the sorting work.

(Projected onto the gaps in the luggage transported by the conveyor)
The luggage sorting system 100 can also provide information by projecting a projected image on the gaps between the luggage transported by the conveyor. The processor 210 of the server 200 transmits information such as a stop of the conveyor belt and a message to the worker to the projection instruction device 30. The projection instruction device 30 instructs the projector 40 to project a projected image including this information (provided information). The projector 40 projects a projected image including the provided information in the gap of the luggage so as not to cover the luggage. The projection position or the projection timing is determined by the projection instruction device 30 instructing the projector 40. The projector 40 may project the projected image at a predetermined projection position or at a timing.

Here, when the provided information is information indicating the stop of the conveyor, the parcel sorting system 100 can alert the worker that the conveyor will be stopped soon before the conveyor is stopped. Further, when the provided information is a message to the worker, the message to the worker includes, for example, notifying the worker of the sorting score (worker score) and the sorting level. In addition, as encouragement to the workers, there are messages such as "greeting", "thank you", "good morning", "well done", "as expected", and "thank you". In addition, as a mental preparation, when notifying in advance that you will be busy, messages such as "Increase the amount of luggage for Tokyo for about 10 minutes from 3 minutes" and "You will be busy in a few minutes" can be mentioned.

FIG. 15 is a diagram showing a projection pattern Q6 in which a projection image Gm including provided information is projected in a gap of a load carried by a transport conveyor in addition to the projection image Ga which is a circular image. In this projection pattern Q6, the projector 40 includes a message of "belt conveyor stop" as a reminder in the gap between the luggage transported by the conveyor belt to Tokyo and the luggage transported next by the conveyor belt to Osaka. The projected image Gm is projected.

Here, the projected image Gm including the characters that provide information is projected in the gap between the luggages, but the projected image Gm is projected on the surface of the conveyor that does not cover the luggage, the periphery of the conveyor, and the like. May be good. Further, the projected image Gm is not limited to characters, but may be an illustration, a symbol, or the like representing the provided information.

As described above, in the projection instruction system 5, the projection instruction device, apart from the projection image Ga including the baggage sorting information, is not directly related to the baggage sorting and raises the motivation of the worker. It is possible to project a projected image Gm including a message such as "one hour left until the end of work".

In addition, the projection pattern that projects the projected image Gm into the gap of the luggage is painted in red on the urgently designated luggage, and when the projected image Ga including the characters "Urgent" is projected, either before or after the urgently designated luggage. The projected image Gm may be projected on an area that does not cover the luggage, such as a gap between the two. In this case, information such as the reason for the urgent designation can be included in the projected image Gm.

As described above, in the projection instruction system 5 according to the first embodiment, the projection instruction device 30 instructs the projector 40 (an example of the image projection device) of the projected image on the luggage. The projection instruction device 30 includes a processor 34, a memory 36 that stores package identification information that identifies each of a plurality of packages to be delivered, and a communication circuit 39 that communicates with the server 200. The processor 34 cooperates with the memory 36 to generate a projected image Gb (an example of the first projected image) indicating the sorting of the corresponding luggage based on the luggage identification information for each luggage stored in the memory 36. Then, the projector 40 is instructed to project the projected image Gb. When the processor 34 receives an external instruction including a change of the baggage identification information from the server 200, the processor 34 indicates a projection image Ga (an example of a second projected image) indicating the sorting of the corresponding baggage based on the changed baggage identification information. ) Is generated, and the projector 40 is instructed to project the projected image Ga.

As a result, the projection instruction device 30 adaptively supports the efficiency of the parcel sorting work and the delivery even when there is an external instruction such as addition, change, or deletion of information about the parcel to be sorted. It can contribute to the efficiency of luggage distribution.

Further, the server 200 acquires the package information from the warehouse control device 400. The package information includes, for example, the sorting amount, the current or daily number of packages (an example of the number of sorted items), and worker information. The processor 34 has acquired information on the sorting amount and the number of sorting of workers, and based on the baggage identification information including the changed sorting information sent from the server 200, the sorting amount of the baggage of a specific sorting destination is one person. When it is determined that the upper limit of sorting of the workers in the above is exceeded, an image indicating help for sorting to a specific sorting destination is generated as a part of the projected image Ga. For example, the processor 34 generates a projected image Ga, which is a circular image of a person in charge number "2" representing a person in charge of sorting packages to Osaka by painting them in blue for packages to Tokyo that are transported by a conveyor. To do. As a result, when the amount of parcels sorted by a specific parcel sorting destination is large, the projection instruction device 30 assigns a worker who sorts the parcels of another sorting destination to the sorting of the specific parcel, and sorts the specific parcels. Can be instructed to support personnel. Therefore, the projection instruction device 30 can equalize the labor of the sorting workers. In addition, delays in sorting packages to a specific sorting destination are suppressed.

Further, the server 200 acquires weather information (an example of weather forecast information) or traffic information from an external organization. The processor 34 determines that the delivery time of the baggage of the specific sorting destination is earlier than the originally scheduled time based on the baggage identification information including the changed sorting information sent from the server 200 that has acquired the weather information or the traffic information. In this case, an image indicating that the package to be sorted to a specific sorting destination is urgently delivered is generated as a part of the projected image Ga. For example, in the case of urgent designation, the processor 34 fills in red and generates a projected image Ga which is a circle image of the characters "Urgent" and the person in charge number "3". As a result, the projection instruction device 30 can instruct to give priority to the work of the sorting destination, which must be urgent.

In addition, the server 200 acquires information that care must be taken in handling a specific package. The processor 34 is careful in handling a specific package based on the package identification information including the changed sorting information sent from the server 200, which has acquired the information that the handling of the specific package needs attention. Is determined to be necessary, an image indicating that caution is required when sorting a specific package is generated as a part of the projected image Ga. For example, the processor 34 fills in blue for a package bound for Tokyo, and generates a projected image Ga which is a circular image of the characters "Caution" and the person in charge number "1". As a result, the projection instruction device 30 can call attention to luggage for which special attention must be paid to sorting, such as luggage for VIPs and luggage packed with cracks.

In addition, the server 200 acquires information on the current load capacity of the load on a specific truck (an example of a delivery vehicle). When the processor 34 determines that the truck cannot be loaded based on the changed sorting information sent from the server 200, which has acquired the information on the current load capacity of the truck, the luggage sorted immediately before is sorted. An image indicating that the next and subsequent packages will be sorted to other trucks is generated as a part of the projected image Ga. For example, the processor 34 fills the baggage bound for Tokyo with blue and generates a projected image Ga which is a circular image of the characters "NEXT" and the person in charge number "1". As a result, the projection instruction device 30 can instruct the worker in real time to load the truck to be sorted into the next truck because the truck currently being loaded is full. Therefore, the worker can sort the luggage by recognizing in advance that it will be loaded on the next truck. Sorting work becomes more efficient.

Further, the projection instruction device 30 is further connected to a label reader 10 that reads the luggage identification information from the label attached to the luggage. The processor 34 stores the package sorting information input from the label reader 10 in the memory 36. As a result, the projection instruction device 30 acquires the package identification information from the label affixed to the package by the label reader 10. Therefore, when the package identification information is changed, the package after the change is changed from the label attached after the change. You can get specific information. In this case, the server 200 does not have to generate the projected image including the changed sorting information. The projection instruction device 30 can instruct the projector 40 to project a projection image including sorting information on the upper surface of the package without interposing a server 200. Therefore, the configuration of the luggage sorting system 100 becomes simple.

In addition, the processor 34 of the server 200 generates a projected image Gm (third projected image) including the provided information. The projection instruction device 30 instructs the projector 40 to project the projected image Gm into the gaps between the plurality of packages to be delivered in order. As a result, the projection instruction device 30 can project a projection image Gm including a message of "conveyor conveyor stop" as a reminder to the worker, and also raises the motivation of the worker, such as "Ganbaro" and "End of work". It is possible to project a projected image Gm including a message such as "1 hour left until".

In addition, the server 200 acquires information on the delivery destination of the package. When the processor 34 determines the loading position of the luggage on the truck based on the changed sorting information sent from the server 200, which has acquired the information on the delivery destination of the luggage, the processor 34 displays an image showing the loading position of the luggage. Generated as part of the projected image Ga. For example, the processor 34 generates a projected image Ga with the word "front" on the upper surface of the luggage bound for Yokohama, which prompts the luggage to be placed in front of the truck bed. In addition, the processor 34 generates a projected image Ga containing the characters "奧" that urges the load to be placed on the back of the truck bed. As a result, when the driver who delivers the truck uses the departure point, the waypoint, and the arrival point as the delivery route and unloads the luggage on site, the work efficiency of loading and unloading is improved.

Further, in the projection instruction system 5, the projection instruction device 30 for instructing the projector 40 of the projected image on the luggage and the server 200 are communicably connected. The projection instruction device 30 has a memory 36 for storing package identification information that identifies each of the plurality of packages to be delivered. The projection instruction device 30 generates a projection image Gb (an example of the first projection image) indicating the sorting of the corresponding luggage based on the luggage identification information including the sorting information for each luggage stored in the memory 36. , Instruct the projector 40 to project the projected image Gb. The server 200 sends an external instruction including a change in the package identification information to the projector 40. When the projector 40 receives an external instruction from the server 200, the projector 40 generates a projected image Ga (an example of a second projected image) indicating the sorting of the corresponding baggage based on the baggage identification information including the changed sorting information. Then, the projector 40 is instructed to project the projected image Ga. As a result, the projection instruction device 30 adaptively supports the efficiency of the parcel sorting work and the delivery even when there is an external instruction such as addition, change, or deletion of information about the parcel to be sorted. It can contribute to the efficiency of luggage distribution.

Further, each time the projection instruction device 30 detects the loading of the projected luggage on the truck by the projected image Ga, the projection instruction device 30 sends the luggage identification information including the capacity information of the loaded (corresponding) luggage to the server 200. The processor 210 of the server 200 calculates the current occupied capacity of a plurality of trucks having different delivery destinations based on the package identification information sent from the projection instruction device 30. The processor 210 of the server 200 generates a UI screen 350 showing the calculation result of the current occupied capacity for each of the plurality of trucks, and displays the display unit 312 of the truck transportation management device 300 and the display unit 412 (display) of the warehouse control device 400. Display on (Example of device). As a result, the delivery manager of the truck, or each worker who sorts to each delivery destination, determines the loading status of the luggage on the truck, for example, how much of the luggage is loaded on the current truck and where is loaded on the next truck. Can be easily grasped.

[Usage example 2 of projection instruction system]
The server 200 acquires the parcel capacity and the sorting progress information of the parcel as the information about the parcel sorted from the parcel sorting system 100, and formulates and changes the truck delivery plan and the staffing plan. In this usage example 2, the server 200 and the package sorting system 100 construct a plan data management system that manages a truck delivery plan and a staffing plan.

First, the luggage capacity can be measured using the image sensor 20 included in the luggage sorting system 100. The image sensor 20 can use a 3D sensor as the distance image sensor 22, and the 3D sensor measures the distance by matching the images of the two cameras.

The server 200 updates the truck delivery plan (for example, a plan related to truck arrangement) in real time based on the package capacity of the package acquired from the package sorting system 100. The server 200 outputs the updated truck delivery plan to the truck transportation management device 300 and the warehouse control device 400.

The truck transport management device 300 arranges trucks using a truck delivery plan that is updated in real time. For example, the truck transport management device 300 planned to have two trucks bound for Tokyo in the warehouse, but if all the luggage was smaller than expected, the two trucks bound for Tokyo were changed to one truck (trucks). You can cancel one). Also, I was planning to have one truck bound for Osaka, but if all the luggage is larger than expected, I can add one truck in a hurry. As a result, the truck transportation management device can efficiently arrange the truck and reduce the operating cost of the truck.

Further, the server 200 updates the truck delivery plan (for example, a plan related to the delivery fee) in real time based on the parcel capacity information acquired from the parcel sorting system 100. The server 200 outputs the updated truck delivery plan to the truck transportation management device 300.

For example, the server 200 may predict future (next day, etc.) sorting, and dynamically change the reception today and the next day's charges. As a result, the truck transport management device 300 can eliminate the inconvenience that the charge is constant regardless of the amount of luggage, that is, regardless of the number of trucks. In this way, dynamic pricing is feasible, in which the required number of trucks is determined by the luggage capacity of the sorted luggage. Therefore, the truck transportation management device can set a low delivery fee for packages to Tokyo on the day when there are few trucks to Tokyo. The truck transportation management device may dynamically predict future charges (next day, etc.), or may determine the delivery charges later based on the amount of luggage on that day.

Next, the sorting progress information can be measured by the package sorting system 100 using the image sensor 20. A color image sensor 24 can be used as the image sensor 20. The color image sensor images the load transported by the transport conveyor and detects the fill color of the projected image projected on the upper surface of the load. The parcel sorting system 100 acquires sorting progress information based on projected images of different colors for each sorting destination.

The server 200 updates the staffing plan in real time based on the sorting progress information acquired from the package sorting system 100. The server 200 outputs the updated staffing plan to the warehouse control device 400.

For example, the server 200 changes the staffing plan in real time based on the luggage sorting progress information acquired from the luggage sorting system 100, and outputs the changed staffing plan information to the warehouse control device 400. The warehouse control device 400 allocates workers according to this staffing plan. For example, if the person in charge of luggage to Tokyo has to sort by one person even on a day when there is an unusually large amount of luggage to Tokyo and during a large number of hours, the sorting work is inefficient. In such a case, the warehouse control device 400 temporarily assigns a highly skilled person to sort the luggage bound for Tokyo on days and hours when the luggage bound for Tokyo is unusually large. Can support the person in charge of luggage. This improves the efficiency of the sorting work.

As described above, the projection instruction system 5 according to the first embodiment is applied to the plan data management system in which the projection instruction device 30 (an example of the sensor device) to which the image sensor 20 is connected and the server 200 are communicably connected. Will be done. The projection instruction device 30 detects information (load capacity information, sorting progress information) related to the packages corresponding to each of the plurality of packages transported on the transfer conveyor 50 (an example of the transfer device) and sends the information to the server 200. The server 200 has a memory 211 for storing plan data (for example, a truck delivery plan, a staffing plan) for each delivery of a plurality of packages. The server 200 updates the plan data stored in the memory 211 based on the information about the package sent from the projection instruction device 30. The server 200 outputs the updated plan data to an external control device (for example, a truck transportation management device 300, a warehouse control device 400) connected to the server 200.

As a result, the server 200 can formulate or update the truck delivery plan by using the information about the package acquired from the projection instruction device 30, for example, the package capacity of the package. Further, the server 200 can formulate or update the staffing plan by using the sorting progress information acquired from the projection instruction device 30.

Further, the projection instruction device 30 uses the distance image sensor 22 included in the image sensor 20 to detect the capacity information of the delivered (corresponding) package as the information related to the package. The server 200 updates the truck delivery plan (an example of the arrangement plan data of the delivery truck for delivering the parcel) as the plan data based on the capacity information of each of the plurality of parcels. As a result, the server 200 can receive the package capacity information from the projection instruction device 30 and output the change information of the truck delivery plan to the truck transportation management device 300 in real time. The truck transport management device 300 can arrange trucks according to this truck delivery plan. Therefore, the truck transport management device 300 can efficiently arrange trucks and reduce the operating cost of the trucks. In addition, the server 200 can receive the package capacity information from the projection instruction device 30, change the truck delivery plan in real time, and change the delivery fee.

Further, the projection instruction device 30 uses the color image sensor 24 included in the image sensor 20 to acquire the sorting progress information of the (corresponding) luggage loaded on the truck as the information regarding the luggage. The server 200 updates the personnel allocation plan (an example of the allocation plan data of the workers who sort the packages) as the plan data based on the sorting progress information of each of the plurality of packages. As a result, the server 200 receives the luggage sorting progress information from the projection instruction device 30 and outputs the change information of the staffing plan to the warehouse control device in real time. The warehouse control device allocates workers according to this staffing plan. The warehouse control device can support the person in charge of luggage to Tokyo by changing the highly skilled person in charge to the arrangement to Tokyo, for example, when there is an unusually large amount of luggage to Tokyo.

Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications, modifications, substitutions, additions, deletions, and equality examples within the scope of the claims. It is understood that it naturally belongs to the technical scope of the present disclosure. In addition, each component in the various embodiments described above may be arbitrarily combined as long as the gist of the invention is not deviated.

For example, in the first embodiment described above, the projected image projected by the projector 40 on the upper surface of the luggage is a circular image, but it may be a polygonal image such as a rectangle or a triangle. Further, the projected image is not limited to a still image, and may be an animation. Animations include blinking the projected image, enlarging / reducing it, and changing the color. Further, the projector may project a projected image not only on the upper surface of the luggage but also on the surface (front, back, side surface, etc.) of the luggage so that the worker can easily perform the sorting work.

This disclosure adaptively supports the efficiency of parcel sorting work and delivery even when there is an external instruction such as addition, change, or deletion of information about the parcel subject to sorting work when sorting parcels. However, it is useful because it can contribute to the efficiency of luggage distribution.
